New version of Centipede for the BBC Micro (in progress)

Postby tricky » Sun Oct 01, 2017 11:32 am

Hi, sorry I've been so slow getting this first demo out, it hasn't been much work, but I've managed to spend nearly no time coding.
You can move (inc through mushrooms), shoot, hit mushrooms and the centipede segments, collide with the centipede and progress to next level if you hit all the segments. The centipede will split if it collides with itself, or if you shoot it.
There is no sound and I think you can shoot a segment while it is exploding!
You can move: [Z], [X], [/] ,[:] (probably ' on emulator) and [RETURN] to fire.
Pressing fire on the joystick will activate joystick + keyboard mode, careful not to click if you have mouse emulating joystick in an emulator.

Things to add:
* fix extra heads spawning, so they don't collide immediately with the centipede.
* player movement blocking by mushrooms.
- working, but could be improved - Dave, can you feel the acceleration ;)
* the flea, drops down the screen spawning mushrooms (does it only drop when there are less than 5 mushrooms in the player's area?)
- flea still needs to be shootable and collide with the player
* the spider, bounces around being a nuisance.
* the scorpion, poisons mushrooms, which cause the centipede to dive until it reaches the player's area when it hits them.
* sound.
* improve control.
+ high-score table and name entry (maybe)
Is there anything else I have missed?
In the arcade ROM, there are graphics for some kind of grass-hopper, does anyone know what it was supposed to do?
I don't think I have ever played millipede, I have heard that it isn't as good as centipede, does anyone think differently?

Good work Tricky, as always! The question everyone's asking though - when is there going to be a 16 colour NULA version? :D

Well, with the beeb sprite ripper (or whatever it is called) and 3 pixels per byte attribute mode, as soon as someone makes it :lol:
Small update, added the flea for when there are 5 or less mushrooms in the player's area (bottom quarter of the screen) - need to fix player-flea collision and make it shootable.
There is a bug that occasionally leaves a double width shot on the screen, I can't remember if it is when you die, or when you complete a level.

Sorry, i've been very slack with this, but I haven't forgotten; lost a day to sound as usual.
Here is a small update with some sound, should support keyboard and joystick (fire to activate, then you can use both).
I've still got nearly 5K free and can't think what to do with it all :lol:
